Beginning with October 1, 2008 we are getting an error stating thet "String was not recognized as a valid DateTime". All dates up to September 30th work without any problems. Are there any known issues with these dates in the WebDateChooser? We are using Infragistics2.WebUI.WebDateChooser.v8.1.dll
HI, did you set the maxdate property to 9/30/2008. If so then October dates would be invalid.
Here is a help link to the webdatechooser maxdate property:
